Geometric observers and particle filtering for controlled active vision
(Georgia Institute of Technology, 2011-08-09)
Visual Search Automation for Unmanned Aerial Vehicles
(Georgia Institute of Technology, 2005-01)
This paper describes the design, development, and
testing of an Unmanned Aerial Vehicle (UAV) with automated
capabilities: searching a prescribed area, identifying a specific
building within that area based on a small ...
A note on linear systems on K-3 surfaces
(Georgia Institute of Technology, 1982-09)
A simple necessary and sufficient condition is given for a general
member of the complete linear system Y to be irreducible and nonsingular where
Y is a reduced, connected curve on a K-3 surface.
A Geometric Approach to Joint 2D Region-Based Segmentation and 3D Pose Estimation Using a 3D Shape Prior
(Georgia Institute of Technology, 2010-03-03)
In this work, we present an approach to jointly segment a rigid object in a two-dimensional (2D) image
and estimate its three-dimensional (3D) pose, using the knowledge of a 3D model. We naturally
couple the two processes ...
A Geometric Snake Model for Segmentation of Medical Imagery
(Georgia Institute of Technology, 1997-04)
We employ the new geometric active contour models, previously formulated, for edge detection and segmentation of magnetic resonance imaging (MRI), computed tomography (CT), and ultrasound medical imagery. Our method is ...
A Skew Toeplitz Approach to the H∞ -Optimal Control of Multivariable Distributed Systems
(Georgia Institute of Technology, 1990-03)
In this paper the problem of the H∞ optimization of multivariable distributed systems in the four block setting is studied. This work is based on several previous papers and employs the skew Toeplitz framework developed ...
Deform PF-MT: Particle Filter With Mode Tracker for Tracking Nonaffine Contour Deformations
(Georgia Institute of Technology, 2010-04)
We propose algorithms for tracking the boundary contour of a deforming object from an image sequence, when the nonaffine (local) deformation over consecutive frames is large and there is overlapping clutter, occlusions, ...
Affine Registration of label maps in Label Space
(Georgia Institute of Technology, 2010-04)
Two key aspects of coupled multi-object shape analysis and atlas generation are the choice of representation and subsequent registration methods used to align the sample set. For example, a typical brain image can be labeled ...
An efficient numerical method for the solution of the L₂optimal mass transfer problem
(Georgia Institute of Technology, 2010-02-05)
In this paper we present a new computationally efficient numerical scheme for the minimizing flow approach for the computation of the optimal L₂mass transport mapping. In contrast to the integration of a time dependent ...
On the H∞ -Optimal Sensitivity Problem for Systems with Delays
(Georgia Institute of Technology, 1987-05-01)
In this paper we extend some of the results of [IEEE Trans. Automat. Control, AC-31 (1986), pp. 763–766] to more general delay systems. In particular, we analyze the effect of the interaction of delays and nonminimum phase ...
